Dumitrascu’s appointment was approved by Rompetrol Rafinare’s shareholders Tuesday, the company said in a statement. His mandate is valid until April 30, 2014.

Dumitrascu took over as OPSPI head at the end of 2012.

At the end of May, Vulpescu was named the Finance Ministry’s representative to the General Assembly of Shareholders of state-owned natural gas transporter Transgaz (TGN.RO). He resigned as OPSPI head in October last year after the privatization of state-owned chemical plant Oltchim (OLT.RO) fell through.

Rompetrol Rafinare, the refining unit of the country’s second-largest oil group Rompetrol, registered gross sales of $884.3 million in the first quarter of 2013, down 19% on the year. Its loss fell 2.4 times to $25.1 million in the first quarter.
